X + y = 9 x + 3y = 13 If (x, y) is the solution to the given system of equations, what is the value of y?

D.) 3

Step-by-step explanation:

x + 3 = 8

x - 3 = 2

so that means x = 5 and y = 3

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

jml angle lkj & angle mj = lm
